Simple logging utility

const { logger } = require('logger');

const log = logger();
log.info('server up and running');
log.error(`an error ocurred: ${err}`);

logger is based on the following components:

• Severity levels
• Formatters
• Writers

Loggers created with logger() are defined with these properties by default. You can customize them with the optional config paramenter

// default config
var log = logger({
  level: 'info',
  formatter: 'json',
  writer: 'stdout'
});

• debug
• info (default)
• error

• json (default, e.g. { "timestamp": 1548614131583, "level": "debug", "message": "..." })
• compact (e.g. info: server up and running)
• verbose (e.g. [27/01/2019 19:38:23] error: server timeout)

• stdout (default)
• file (TODO)
• http (TODO)

Probably you will need to log messages to multiple destinations with different formatters and severity levels for each one

You can easily achieve this by passing to logger() an array of config objects

var log = logger([
  {
    level: 'info',
    formatter: 'compact',
    writer: 'stdout'
  },
  {
    level: 'error',
    formatter: 'verbose',
    writer: 'file'
  }
]);
